This doesn't exactly fall under minor league information, but it does affect how to determine prospects.  The Washington Post today published a chart titled "Lowest Batting Averagge on Balls Put in Play, Career".  Good - this is a good way to tell if BABIP shows luck or skill.  When I look at the top six for the American League: Jerrod Washburn, Tim Wakefield, Paul Byrd, Steve Trachsel, Mark Buehrle, and Brett Tomko, I don't see too many stars (Halladay was 7th and Mussina 8th), and think that once a ball is hit, it's all luck as to whether or not a pitcher is successful.  But then I look at the top six of the National League: Barry Zito, Pedro Martinez, Tom Glavine, John Smoltz, Greg Maddux, and Tim Hudson (followed by Moyer and Park), and with four Hall of Famers and two guys who've made a few all-star games, you gotta think that BABIP is a reflection of skill.  I still don't know.  What do you guys think?
